Since 1987, we've powered over 1.3 million spas with our support systems. We 100% can power your hot tub
with our robust equipment. To get a quotation, you may email photos of your spa support systems to
sales@acuraspa.com.
Call us while you are on our website at 951-684-6667 ext. 223. We will guide you
to design a new spa pack for your hot tub and answer all your hot tub questions.

Spa Controls Digital or Pneumatic:
Hot tub controls are made to manage the mode of operation in a spa regardless of the spa brand
or manufacturer. Most spa manufacturers do not design their spa controls or heaters. Spa manufacturers
purchase the hot tub controls from different vendors. In many cases, vendors will private label
the spa control to the spa manufacturers. All our controls are made to heat the water and manage
the pump(s) as well as other accessories in your spa. You may easily replace your existing spa
control with ours regardless of your hot tub brand. You need to check the dimensions and make sure
you have selected the proper size control and heater for your application. You also must purchase
the plugs for all your accessories. All plugs are available for you to select on table (3). Incoming power
must be wired to our terminal block and must be done by a licensed electrician.

Preventing Heater Dry-Fire in portable hot tubs, we offer a solution:
Air locks have been the deadly enemy of spa heaters in hot tub applications. Hot tub heaters
are destroyed if air is trapped in the heater manifold. Especially after emptying and refilling
their spa, consumers often forget to bleed the air out of the hot tub plumbing. This usually results
in a spa heater "dry fire" and costly hot tub heater replacement.
Hot tub manufacturers do not warrant submersible spa heaters against dry fire. Submersible hot tub
heaters are 100% efficient, but this makes dry fire a real concern.
Acura Spa Systems engineered a simple, inexpensive, yet most innovative device to automatically
bleed air out of the spa heater plumbing, preventing heater dry fire and, in many cases, helps prime
the spa pump. Make sure your spa heater is protected.

Electrical Connections: Incoming Power to Control Box

All electrical work must be done by a licensed electrician.

Please provide licensed electrician's state license number.

Using a working voltmeter, test all incoming wires for proper voltages before you hook them
to the Main Power Terminal Block. Your voltmeter should read the following:

All spas and hot tubs must be protected by GFCI as required per NEC and UL 1563.
Read and understand the instructions provided by your GFCI manufacturer. Identify the lines
and the loads of the GFCI (improperly connected, your GFCI will short to ground).
Make sure to connect ony the loads from the GFCI to our control box.

Read the wiring diagram on the electrical pump motor. An example of this diagram is shown in
Fig. (b) below. Note that this diagram is on an A.O. Smith motor, other motors will have different
but similar labels. By law, ALL electric motor manufacturers MUST provide a wiring diagram on the motor.

Wiring the 14/4 cord from our digital control to the pump motors (see Fig. (b)):

Connect cord Black wire to terminal marked "High speed" on the motor.

Connect cord Red wire to terminal marked "Low speed" on the motor.

Connect cord White wire to terminal marked "Common" or "Line" on the motor.

Improper connection to the GFCI will cause the GFCI to trip:

On all Digital controls in the hot tub industry, you have a transformer (120 Volts AC to 12 Volts AC to 5 Volts DC)
The winding on the transformer reads a continuity of 30 OHMS between the black (L1) and white (Neutral) wires; this is normal.
The GFCI must be connected properly per the GFCI manufacturer installation instructions.
The GFCI installer must understand the difference between Line (incoming wire connections to the GFCI) and Load (outgoing wire connections from the GFCI to the spa control box).
A common mistake GFCI installers do is wiring the Neutral wires improperly by reversing the Line and Load connections on the GFCI.
The Line neutral wire must be connected to the Neutral Bar and the Load neutral wire must be connected to the spa control box.
Please make the proper electrical connections on your GFCI.
To prove that our control box is good (temporarily and for testing only), all you need to do is disconnect your GFCI from your electrical circuitry and connect directly to a regular breaker.

Any burned circuitry on the PC board is a result of a direct short from improper electrical connections and voids Acura Spa Systems, Inc. Warranty.

At Acura Spa Systems, before we ship, all controls are 100% water tested in addtion to the dielectric and Mega ohm safety tests as required by UL 1563.

When requesting warranty work from Acura Spa Systems, please read our limited warranty

A copy of your paid invoice from Acura Spa Systems, Inc. must accompany the Warranty Claim Form. All warranty claims
products must be shipped to Acura Spa Systems, Inc. freight prepaid and fully insured.

Automatic Air Bleeder Installation on any Portable Hot Tub:

Find a rigid PVC pipe or pipe fitting [Figure (2)] as close as possible to the heater manifold.
The AABV can be instaqlled before or after the heater manifold. The AABV must be installed
on the Pressure side of the pump.

Using a 7/16" drill bit (drill bit size 0.4375" or 7.4mm [Figure (3)]), drill a hole in the
rigid PVC pipe as shown in Figure (4).

Pump Installation/Replacement Information:

Electrical connections to pump motors:
We do not supply pumps cords unless ordered. When connecting an electrical cord to the pump
motor, make sure to look at the motor voltage located on the motor nameplate. Motor voltage
may be different from the incoming voltage to the electrical control box (for example, the
motor voltage may be 115V and the electrical control box voltage is 240V). All motors are
supplied with a wiring diagram decal located on the body of the new motor. Connect the wires
to the new motor according to the wiring diagram on the new motor. When removing your existing
power cord from your old pump motor, we recommend you mark the wires for "common" or "Line",
"High Speed", "Low Speed" (Low Speed only if you have a 2-speed motor).

Unions and pump thread tolerance between pump brands:
Even though various pump brands may use the same thread style, thread tolerances between the
pump thread and the connecting nut may vary between production dates. At Acura Spa Systems, Inc.
we keep our tolerances at minimum and should not affect you when replacing your Acura Spa pump and/or
connecting nut. However, we cannot control other brands production tolerances. This means if you
replace another brand pump with an Acura Spa pump, you may need to replace your existing unions with ours.
Throughout the years, many customers have successfully replaced their existing spa pump made by other
brands with ours using their existing plumbing connections.
